InRoads File Types

Below is a list of the primary file types used for InRoads in the road design process. Surface File (.dtm) – Stores point, breakline, boundary, and triangle data defining existing ground and design surfaces. Multiple surface files may be open at the same time. Geometry File (.alg) – Stores geometric data such as horizontal and vertical alignments, COGO points, and superelevation definitions. Multiple geometry files may be open for editing at the same time. Template Library (.itl) – Stores templates made up of components. The components of a template can be open or closed. A simple closed component is used typically to represent a section of pavement. An end condition is a special open-shaped component which define how side slopes are designed. Only one template library may be open for editing at a given time. Roadway Design File (.ird) – Stores information defining which templates are applied at which station along an alignment. Only one roadway design file may be open for editing at a given time. XML Data (.xml) – Stores the bulk data required to build InRoads reports. See the Style Sheet files below for additional information. Project File (.rwk) – An easy method to load and save a number of InRoads data files in a single operation. No InRoads data is stored in this file, it is just an ASCII file that lists the other InRoads external files used for a project. Preference (.xin) – Stores the preferences accessible on each dialog box, feature style definitions, and named symbology definitions. Also stores preferences for geometric (point, line, curve, and spiral) elements. These style definitions are used when the geometric elements are displayed in the graphics file. Only one Preference file can be open at a time. Drafting Notes (.dft) – Stores note definitions created with the various note placement tools found on the Drafting menu. Style Sheets (.xsl) – A definition file that formats data in an .xml file into a finished report.

Retrieving InRoads Base Files

InRoads Base files are created and maintained by the Performance and Development Branch of Roadway Design. These files simplify InRoads Workflows and aid in CADD Standardization. Below is a list of InRoads Base files. Template Library (.itl) Preference (.xin) Drafting Notes (.dft) InRoads Base files are located at the file path: R:\CADD_Support\Design\InRoads\ (ODOT Roadway Design use only) These files should always be copied from the R: drive and pasted into the Project InRoads folder. To copy and paste a file follow the following steps.

1. In Windows desktop double click on the Computer Icon. 2. Navigate to the InRoads file folder on the R:\ drive 3. Holding down the control button select the base files that are to be copied. 4. Right-click any of the base files that were selected. 5. Select Copy from the menu. 6. Navigate to the InRoads folder of the project files. 7. Right click and select Paste from the menu.

After these files are copied and pasted to the project inroads file they will need to be renamed to follow naming conventions.


6.2.1

Internal Naming Conventions Naming of Corridors, Surfaces, and Alignments within InRoads should always follow the external naming conventions. See Section 1 of the CADD Standard for external naming convention. Corridors- When a new corridor is created in InRoads Designer, the corridor name should match the surface that will eventually be created from the corridor. If the corridor was misnamed when originally created simply highlight the corridor in the corridor dialog box and type in a new name and click the Change button.

Surfaces- If the Corridor name already follows naming convention simply turn the checkbox on for the option New Surface for Each Corridor when creating the surface to ensure that the surface name matches the Corridor name.

To change the name of the surface after it has been created, use the InRoads Rename Surface command (InRoads>Surface>Rename Surface) to change the name. Alignments- Alignments should follow naming conventions of the alignments as shown in Section 1 when creating new alignments. When an alignment is created by survey it is necessary to change the name of the alignment. To do this, use the InRoads Rename Geometry Command (InRoads>Geometry>Rename Geometry).


6.3.1

Alignment and Surfacing Styles The styles control how surfaces and alignments look when displayed in MicroStation. Styles are located in the preference file (.xin). If a style is not found make sure the latest version of the preference file is loaded. Alignments There are four primary alignment styles and two detour styles. proposed 50- This style is for showing proposed (CLR) alignments at 50 scale. proposed 100- This style is for showing proposed (CLR) alignments at 100 scale. Existing 50- *This style is for showing existing (A001) alignments at 50 scale. Existing 100- *This style is for showing existing (A001) alignments at 100 scale. Detour 50- This style is for showing detour alignments at 50 scale. Detour 100- This style is for showing detour alignments at 100 scale. * The Existing styles should not be applied to the vertical alignments. A001 and CRL verticals are proposed and will need to be annotated using the proposed styles. To change an alignment style use InRoads Active Geometry command (InRoads>Geometry>Active Geometry). Surfaces There are two primary surface styles. Design Surface- This style is for showing new surfaces on the Cross Sections and if necessary profiles. Using this style will result in the surface showing up as a thick red line. Existing- This style is for showing existing surfaces on the Cross Sections and Profiles. Using this style will result in a green dashed line when viewing surfaces. To change the style of the surface:

1. Right click the surface in InRoads Workspace bar and select Properties from the menu.

2. Click on the Advanced tab and change the symbology setting to the desired style.

6.5.1

Feature Naming Conventions Every Feature in the Template has a name. Having a convention for naming the features is important so that anybody using the template or surface can use the surface. Below is a list of the feature names and what they stand for CL = Centerline of the pavement. Normally it is the CRL or the CL survey of the corridor EOD = Edge of Driving Lane. EOS = Edge of Shoulder EOP = Edge of Pavement EOW = Edge of Wedge. This pertains to the edge of the asphalt wedge TOA = Edge of the top of aggregate Base. BOA = Edge of the bottom of aggregate Base. EOB = Edge of Backfill CLS = Point on the subgrade directly underneath the centerline of pavement. EODS = Point on the subgrade directly underneath the edge of driving lane. EOSS = Point on the subgrade directly underneath the edge of shoulder. EOWS = Point on the subgrade where the wedge of the asphalt ends. CZ = Clearzone DB = Outside edge of the typical ditch bottom. DBSLP = Top of the cut slope where the typical ditch is cut. Fill 1:6 = End of the fill slope where a 1:6 slope is created. Fill 1:4 = End of the fill slope where a 1:4 slope is created. Fill 1:3 = End of the fill slope where a 1:3 slope is created. SPFS 1:6 = End of the Foreslope of the special ditch. SPFS 1:4 = End of the Foreslope of the special ditch. SPFS 1:3 = End of the Foreslope of the special ditch. SPDB 1:6 = Outside edge of the special ditch bottom. SPDB 1:4 = Outside edge of the special ditch bottom. SPDB 1:3 = Outside edge of the special ditch bottom. SPBSLP 1:6 = Top of the backslope after the special ditch. SPBSLP 1:4 = Top of the backslope after the special ditch. SPBSLP 1:3 = Top of the backslope after the special ditch.


6.6.1

Project Defaults The Project Defaults command sets the default directory locations for opening/saving files and also automatically opens design preference when InRoads is activated. The top portion of the dialog box “Default Preferences” opens files for: General Preference (.ini), Geometry Style (.ini), Survey Feature Table (.fwf), Survey Preference (.fxp). The bottom portion of the dialog box “Default Directories” saves path locations for all file types that can be accessed through the File/Open and File/Save As dialog boxes. These include Project (.rwk), Surface (.dtm), Geometry (.alg), Typical Section Library (.tml), Roadway Library (.rwl), Survey Data (.fwd), Storm and Sanitary (.sdb). All other files, which are opened or saved throughout the program, use the Project Default Directory setting. The number of project defaults allowed is virtually limitless they can be set for several different type projects. They are user specific and unless exported can only be accessed under the user profile of the original creator. To set up Project Defaults for a workflow in InRoads select File>Project Defaults (Q>6) Click the new button to create a new Project Default.


6.7.1

Project Defaults Key in a name (e.g. project number) (Make it a name that describes the project) Select the OK button on the New Configuration window. Once an empty project default is created, The Item key-in boxes will become available to fill in. Click into the white box beside the Preferences (*.xin): and select the Browse button. From the Open window, navigate to the correct file and select the Open button. The path and file name will appear in the Default Preferences. Repeat this process for each item to have it load automatically. Do not set a path for Style Sheet (*.xsl) – Roadway Design uses the default Style Sheets for Reports. Changing the path will cause the reports not to function. Once all desired lines are filled choose the Apply button and then Close.


6.7.2


The following list contains several locations surfaces commonly change. Horizontal Events and additional CrossSection stations should be added at these locations to ensure the design surface and earthwork are accurate. Note: Surface Models are commonly generated on 25’ intervals but CrossSections are cut at 100’ intervals. If a design change happens at a +25, +50, or +75 location a Horizontal Event and CrossSection should be added to represent that change.

6.8.2

Superelevation Tables For InRoads SS2, superelevation tables (*.sup) were developed specifically for ODOT’s use. Superelevation tables are based on speed and maximum superelevation rate. Superelevation tables are used with the Superelevation Table Wizard found in the Roadway Modeler. Superelevation tables are located at the following path: R:\CADD_Support\Design\InRoads\Superelevation The following is a list of available Superelevation tables: 25mph06.sup 30mph06.sup 30mph08.sup 35mph06.sup 35mph08.sup 40mph06.sup 40mph08.sup 45mph06.sup 45mph08.sup 50mph06.sup 50mph08.sup 55mph06.sup 55mph08.sup 60mph06.sup 60mph08.sup 65mph06.sup 65mph08.sup 70mph06.sup 70mph08.sup 75mph06.sup 75mph08.sup 80mph06.sup
